Scenario testing in VITAL Online refers to the process of determining the maximum amount of hang up and minimum batch size which will cause the Action Level to move between 1 to 2 for a specific cross contact allergen due to processing. To perform scenario testing on a cross contact due to processing, follow the instructions below:
Step 1. Open “Step 4: Processing” of VITAL Online and click on the relevant cross contact due to processing
Step 2. Click on the SCENARIO TESTING button (Figure 1)
Figure 1: a cross contact due to processing in Step 4: Processing in VITAL Online – the “SCENARIO TESTING” button is below the input boxes
Step 3. The results indicate the hang up and batch size amounts relevant for Action Level 1 and Action Level 2. The figure below indicates that where all other inputted variables remain constant and the hang up is less than 1.729166 g, the outcome for this allergen will be Action Level 1. Where all other inputted variables remain constant and batch size is greater than 231325 kg, then the outcome for this allergen will be Action Level 1.
Figure 2: An example of the results from scenario testing
- Scenario testing can be carried out on a cross contact allergen due to processing in VITAL Online. However, similar results to understand the maximum amount of cross contact from an ingredient for Action Level 1 are also useful and can be calculated separately.
- Scenario testing for a cross contact due to processing (as described in the example above) takes into account any other cross contact from that allergen from other processing inputs or due to cross contact added from ingredients.
- It is important to note that these figures are not designed to be used in a prescriptive sense or as a target – however, scenario testing is designed to easily give access to the figures which indicate when the product will move from Action 1 to Action Level 2 where this information in helpful to understand to further understand the affect and risk of a cross contact due to processing.
- It is helpful to know these figures to better understand the results from VITAL Online in terms of risk and these figures can be applied to multiple scenarios. For example, these figures can give you some guidance about the amount of hang up which is significant in terms of cross contact – is it 1kg or 0.5g? There is a big difference in these amounts, and perhaps they can add to decisions about resource allocation, cleaning etc.
